Graphical Abstract

The synthesis and properties of corannulenes bearing up to five ferrocenyl groups are described. All compounds were investigated electrochemically to elucidate the interactions in the multiferrocenylated corannulenes. Additionally, several molecular structures were confirmed by single-crystal X-ray analyses and are discussed with respect to those of previously studied corannulenes.

Abstract

The syntheses and properties of corannulenes bearing different numbers and types of ferrocenyl groups are described. Six different monoferrocenylated corannulenes were synthesized, and the crystal structure of 1-corannulenyl-1′-(ferrocenyl)benzene was elucidated by single-crystal X-ray analysis. Further, diferrocenylated corannulenes bearing methyl or trifluoromethyl groups are reported. Buckybowls with four and five ferrocenyl substituents were synthesized from tetrabromocorannulene and the symmetrical pentachlorocorannulene. The molecular structure and nutshell-like crystal packing of a tetraferrocenylated corannulene was determined by single-crystal X-ray analysis. Additionally, all compounds presented herein were subjected to electrochemical and optical measurements in solution.
